Documentation and Monitoring of World Heritage Sites Using Integrated Surveying Techniques: Practical Case ?Hofkirche?

Documentation and conservation of cultural heritage sites are being increasingly seen as tasks of national, ultimately international priority. Different types of surveying techniques including photogrammetry are used in the field of archaeology for excavation, monitoring, and documentation of the world heritage sites. The main purpose of this paper is to show the ability of documenting and monitoring of the world heritage sites using the integration of some surveying techniques. The Hofkirche in Innsbruck, Austria is the last existing gothic hall church, well known for German Emperor Maximilian I. 's tomb and its black bronze statues. At the end of the 18th century, an earthquake seriously damaged Hofkirche. To investigate the earthquake influence on this church structure, e. g. the inclination of pillars of the church has been observed and shows significant values. Using di gital photogrammetry and reflectorless tachymetry in measurements yield to the geometry of deformed sections of vaults. The possibility of integrating both measuring techniques as well as the advantages and disadvantages of these surveying techniques to document and monitor the world heritage sites will be shown.
